Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a seal member used for a connecting portion of a building material mold.

[Prior art] Aluminum molds have been used as building materials for construction, and because they are easy to cut and punch, and are light and resistant to rust, they can be used for interior and exterior of buildings and exteriors of general houses. Widely used.

As one of the structures using such a mold material, there is a skylight provided on the roof of a building or a general house. The skylight is formed by forming a skeleton of a square shape, a kamaboko shape, a dome shape, or the like with a mold material, and inserting glass into the skeleton.

In forming the skeleton of the skylight, the mold members may be connected in the longitudinal direction. In this connection, the respective mold members supported by appropriate supporting means are connected by abutting their end faces. When connecting such mold members, it is necessary to seal the connection portion so that rainwater does not leak from the connection portion. As a seal member for this,
Conventionally, a seal member as shown in FIG. 5 has been used. As shown in the figure, a sealing member C made of a synthetic resin having a cross-sectional shape that matches the shape of the bottom portion of the mold material A is fitted into the bottom portion of the mold material A in about half of its longitudinal direction, and the other half is The mold material B (indicated by an alternate long and short dash line in the figure) was fitted into the bottom portion to seal between the mold materials.

[Problems to be solved by the device]

However, in the conventional sealing member as described above, in the case where the mold member A is inclined downward from the mold member A to the mold member B, it penetrates through the joint groove of the glass (not shown) or the like through the side groove portion a of the mold member A in rainy weather. There is a problem in that the water flowing as a result infiltrates between the side groove portion a and the seal member C, leaks from between the seal member C and the back surface of the mold material B, travels along the back surface of the mold material B, and drops downward.

The problem to be solved by the present invention is to obtain a seal member in which rainwater does not leak from a mold member connecting portion.

[Means for solving the problem]

The present invention relates to a sealing member for a connecting portion, which is formed by abutting and connecting end faces of a mold material having bottom surfaces and both side walls rising from the bottom surface and outer side groove portions of the both side walls, the seal member being formed along the outer shape of the bottom portion of the mold material. A hole die is formed which has an inner surface shape and covers the entire inner circumference of the bottom surface of the mold member and the predetermined height of the side walls to a predetermined length along the longitudinal direction of the mold member from only the central portion in the longitudinal direction to one side. And, the upper portion of the hole die that covers the side groove portion of the mold material has a groove shape,
It is a seal member for a rubber mold material connecting portion.

[Action]

In the seal member of the present invention, the hole die formed on one side in the longitudinal direction of the seal member is fitted into the end face of one mold member, and the other side is brought into close contact with the bottom face and both side walls of the other mold member, so that the connecting portion It is possible to make a leak-proof seal.

〔Example〕

FIG. 1 is a perspective view showing a seal member according to an embodiment of the present invention, FIG. 2 is an exploded perspective view showing a usage state of the seal member, and FIG. 3 is a perspective view showing an example of a mold member connecting portion. Is.

The present embodiment is an example of a seal member used in a connecting portion between a mold material Sa and a mold material Sb that form a skeleton of a skylight as shown in FIG. In the figure, Sc is a mold material that constitutes the foundation,
G is glass.

The seal member 1 is composed of a bottom side 2, a side wall 3 and a hole die 4. The bottom side 2 has a shape in close contact with the bottom surface S ₁ of the mold material Sa or Sb, and the side wall 3 has a shape in close contact with both side walls S ₂ of the mold material Sa or Sb. The hole die 4 is formed on one side as viewed in the longitudinal direction of the die material, and its shape matches the shape of the lower part of the end surface of the die material Sa or Sb. The material of the seal member 1 is rubber having elasticity, and the seal member 1 is a mold material.
When fitted into the end surface of Sa or Sb, the seal member 1 comes into close contact with the bottom and side walls of the mold material Sa or Sb and both surfaces of each rib.

When this seal member 1 is used, the hole die 4 formed on one side of the seal member 1 is fitted into the bottom end surface of the mold material Sa, and the bottom side 2 and the side wall 3 formed on the other side are formed on the bottom surface and side wall surface of the mold material Sb. Fit in.

In the state where the mold members Sa and Sb and the seal member 1 are in close contact with each other, the water flowing in the side groove portion of the mold member Sb passes over the upper surface of the seal member 1 as shown by an arrow D in FIG. As it flows into the gutter, water will flow into the mold material Sa as before.
Or, it does not drop down along the back surface of Sb.

Further, since the seal member 1 is elastic, it is possible to sufficiently secure the sealability even if there is an intersection angle of about 10 to 15 degrees between the two mold members to be connected.

In addition, in the above embodiment, the hole type 4 of the seal member 1 is used.
Is a shape that matches the shape of the lower part of the end surface of the mold material Sa or Sb, but if the shape of the end surface of the mold material is simple, it may be a shape that matches not only the lower part of the end surface but also the upper part. it can.

Further, although the above description has been made by taking the mold material constituting the skylight as an example, it goes without saying that the seal member of the present invention can be applied to the mold material used for other purposes.

[Effect of device]

 The sealing member of the present invention has the following effects.

Since the seal member is formed with a hole die that covers the entire inner circumference of the bottom surface of the die material to be connected and the predetermined height of both side walls along the longitudinal direction of the die material by a predetermined length, one die material (lower side)
When the end portion of is fitted, a high sealing property with the other mold material (upper side) can be obtained. Further, since the upper portion of the hole die that covers the side groove portion of the mold material has a groove shape, water flowing through the side groove portion of the mold material passes over the upper surface of the seal member and flows into the side groove portion of the downstream mold material. Therefore, water does not drop down along the back surface of the mold material.

There is no leakage of rainwater from the connecting part when it is used for connecting a mold material as a constituent member of a roof or a skylight.

Since it has elasticity, it can be used also when connecting mold members at a slight angle.
